Thanks to its vasoconstrictive power, caffeine is often used in eye-contour care to tighten blood vessels, thereby reducing bags and dark rings. Its effectiveness is also due to its diuretic properties, which, in addition to decreasing puffiness around eyes, helps to reduce the appearance of cellulite. In fact, many studies have confirmed caffeine’s ability to eliminate excess water in the tissues and to reduce the size of skin’s fat cells. The result: less visible dimpling and firmer skin. It’s no coincidence that almost all anti-cellulite products are bursting with caffeine ... it goes to show that coffee has not yet finished invading the world of beauty!
